Title: Continuous polymerisation vessel - with fixed guide plates between revolving drum and vessel wall
Inventor: KIENATH HANS DIPL ING
IPC: B01F27/73
Filed: 1971-08-25
Abstract: A continuous prepn. appts. for polymers comprises a double-walled, heated, cylindrical, horizontal-shaft housing and an internal, rotating drum with its horizontal axis mounted on external bearings; this drum, by its rotation, raises a thin polymer film at one side and drops it at the other side into the sump of polymer which extends not higher than the shaft axis. In the space between the revolving drum and the housing up to the axis level, fixed guide blades are mounted obliquely so as to impart an axial motion to this rotated polymer film. This progressively leads the polymer towards the discharge opening. Pref., there is an appreciable gap between the fixed vanes and the inner wall of the vessel. The method ensures regular proplusion of the mixt. along the cylinder, keeps the film thin and ensures that it is wiped off the drum into the sump. Dead corners are avoided.

Title: Channel amplifier tube HV supply cct. - has push-pull oscillator with stabilised output voltage with series voltage supply cascade
Inventor: BERTHOLD HANSJOACHIM
IPC: H01J43/30
Filed: 1972-06-15
Abstract: The high voltage supply circuit is intended for a channel amplifier tube, coupled to a constant high voltage. A push-pull oscillator with stabilised output voltage is connected in series to a cascade, having a middle input for voltage supply of the tube anode and cathode. In order to generate input voltage for a second push-pull oscillator a further cascade is series connected. The tube output is earthed. The output voltage of the second push-pull oscillator is adjustable by an adjustable Zener diode which can be energised across a photoresistor. The circuit is suitable for brightness control of the channel amplifier tube, whenever the dependence of a physical magnitude on the function of supply voltage is required with high ohmic inputs.

Title: Multi-stage filter to break oil emulsions - having horizontal outer shell to separate and collect water phase
Inventor: POETZ KARL
IPC: B01D17/04
Filed: 1973-07-07
Abstract: Multistage filter for destroying emulsions of water and liquid hydrocarbons and separating out the water phase, has two filter stages. In the first the emulsion is broken down while in the second the water phase is separated off. At least the second stage consists of a horizontal filter shell, the bottom sector of which is impervious and allows water to collect and be drained off. The filter shell is arranged eccentrically in the cylindrical filter housing, with the widest spacing being on the outlet side. This is underneath the shell. The filter is used for purifying and cleaning hydrocarbon feeds. The horizontal arrangements means that the size need not be limited to the available lengths of vertical filter elements. This type of construction reduces costs even for high duty filters.

Title: Weld flattening of longitudinally welded tubes - using a roller with a double eccentric drive
Inventor: GUST KARL
IPC: B21C37/08
Filed: 1973-11-09
Abstract: Longitudinal seam welds in tubes are flattened by a roller, the contact point of which follows an elliptical path whose major axis is parallel to or forms an acute angle with the tube axis. Appts. for flattening longitudinal seam welds in small dia. tubes includes a roller mounted on an eccentric shaft which is mounted eccentrically is a bearing of a guide frame, the eccentric shaft and the bearing being driven in opposed directions and their drives being connected by gears. The roller co-operates with a conventional reciprocating plug which is synchronously controllable with a lower roller. The roller, because of the double eccentric drive, acts in the same manner as a roller of much greater dia. and provides a smooth application of pressure over a greater distance than in prior appts. The reduced number of roller impacts provides a reduction in noise during operation.
